Healy power

I read with interest Brian Newton’s recent letter advocating support for a $95 million, 30-year investment in buying and re-starting the experimental coal fired power plant in Healy. He suggested it will keep your electric rates low and look toward the future.

Newton failed to mention the $95 million investment which, if instead was invested in the proven wind resource at Eva Creek near Healy, could provide half as much electricity with no fuel cost and no carbon output. Long term, a $0 fuel charge with a wind farm vs. a fuel charge subject to new regulation and pending carbon taxes is a better deal, but most of the GVEA board and management don’t appear to see this. The only way GVEA said they’d do Eva Creek is if they get a grant. Should we wonder why they don’t find a grant for the coal plant. Oh, darn, I forgot, both the state and feds already provided $315 million for it and still GVEA needs more.

GVEA has continued to raise rates to pay for loans for numerous capital projects in years past, not just the fuel cost. Don’t expect your rates to go down with another coal plant. In fact, the rate not tied to fuel cost just went up again. We still have to pay off loans, including a new one for more than $65 million for regular annual construction and maintenance.

What about an energy efficient appliance replacement program? GVEA could provide a subsidy to ratepayers equal to the reduced consumption across a period of time. But wait, they don’t want electricity usage to go down because they’ll need to raise the service charge again instead of making oil the boogeyman. Is there something wrong with this picture?

It seems hard for the entrenched to visualize a sustainable future. While GVEA’s attempt to get the membership to give up ownership of three-fourths of the utility’s assets a few years ago failed, I bet they could sell us on a 25 megawatt wind farm. Or give you a energy efficient refrigerator.

He took his project to Delta but it is not 'up and running'. Winds in both Healy and Delta are not constant, as ocean shore winds are. The wind mills can be stagnant and non productive for days on end. Not only does this mean days of no electrical output but it also causes 'bumps' in the line which tends to fry all our electrical gadgets. Wind power is great, just not in the Interior. It needs to be where the speeds are contant.

Well, that's the first time I've ever seen this point made, and it's a good one. Hindsight is great, of course, but if they'd spent the same money on windmills 20 years ago we'd have had 20 years of electricity to show for it today.

Since wind speed is not constant, a wind farm's annual energy production is never as much as the sum of the generator nameplate ratings multiplied by the total hours in a year. The ratio of actual productivity in a year to this theoretical maximum is called the capacity factor. Typical capacity factors are 20–40%, with values at the upper end of the range in particularly favourable sites.[15] For example, a 1 MW turbine with a capacity factor of 35% will not produce 8,760 MW·h in a year (1 × 24 × 365), but only 1 × 0.35 × 24 × 365 = 3,066 MW·h, averaging to 0.35 MW.

Interconnecting ten or more wind farms can allow an average of 33% of the total energy produced to be used as reliable, baseload electric power, as long as minimum criteria are met for wind speed and turbine height.

In other words... wind power is not necessarily all that it is cracked up to be. Furthermore, wind power is not capable of being an on-demand energy source... but coal is.

user6244, Nice videos and such. Let me guess, is it a Usibelli production?

If by, "us", you mean Denali Borough, then don't hold your breath while waiting for wind generators! 'This is a coal town', was a common phrase heard when a wind generation project was proposed here.A private developer was funding the entire project.

You should have heard the screaming! The claim was that the wind generators would kill thousands of migrating birds. With a blade that rotates at 17 RPM? The towers are so tall that the flocks of birds will fly into them and die! I don't know about you, but I haven't noticed dead birds dripping from the micro wave towers or the towers that support the intertie lines!

There are a lot of environmentally concerned folks that live here but I never heard much support for wind power, from that segment either. To make a long story short, the developer took his project to Delta Junction and is up and running. Wouldn't you think that a Borough that relies on the tourist's dollars, would try to show some progress to environmentally sound power generation? It could even be a tourist attraction!

Go figure!!!
